Title: Plasma arc utilizing machine
Inventor: MORIGUCHI HARUO
IPC: B23K10/00
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To facilitate generation of a pilot arc.

Title: Speed control method for induction motor
Inventor: TOBARI KAZUAKI
IPC: H02P23/12
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent torque shortage in a zero-speed region which is caused by speed estimation error of a speed-sensorless vector control method by controlling a magnetic flux axis current to be at least the ordinary time value, when a speed command value is at most a specified value, replacing a frequency command value with a speed estimation value, and performing operation on the basis of the speed command value. SOLUTION: In speed-sensorless vector control, a speed estimation value ωr ' from a speed estimation unit 4 contains speed estimation error caused by change of a motor constant or the like, so that torque shortage is apt to be generated especially in a zero-speed region. In the zero-speed region, a magnetic flux (d) axis current command unit 11 sets a current command value id** to be a value in which Δiα is added to a reference value id* at normal times, and control the current command value to be a value corresponding to the maximum load torque. Through a switching unit 9, a speed command value ωr * is selected instead of a speed estimation value ωr ' at normal times, and an output frequency of a converter 2 is controlled, in response to the speed command value ωr *.  Through the control of the output current and the output frequency of the converter 2, torque shortage in the zero-speed region can be resolved.

Title: Medium to be recorded for ink-jet
Inventor: SASAKI TARO
IPC: C08J7/04
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To improve ink absorbing properties, water resistance and light fastness of image by forming an ink absorbing layer consisting of an ink absorbing resin on a dye fixing layer consisting of an interlaminar compd. for receiving and holding a water-soluble dye by intercalation reaction and a binder resin. SOLUTION: A dye fixing layer 2 consisting of an interlaminar compd. for receiving and holding a water-soluble dye by intercalation reaction and a binder resin is formed on a base material 1. In addition, an ink absorbing layer 3 consisting of an ink absorbing resin is formed on the dye fixing layer 2. Therefore, as the ink absorbing layer 3 is formed on the dye absorbing layer 2, such an ink that can not be received by the dye fixing layer 2 can be absorbed. In addition, as the dye fixing layer 2 wherein dye image is fixed is not brought into direct contact with water, water resistance of the image is improved. It is possible thereby to form the image with durability being equal to a silver salt photograph.

Title: Common line call processing signal system
Inventor: TANAKA HIDENORI
IPC: H04M7/06
Filed: 1991-12-26
Abstract: PURPOSE:To prevent the signal sequence inversion of a common line call processing signal with different priority caused due to congestion of a common line telephone signal network and communication congestion between processors. CONSTITUTION:An address signal and an interrupt signal sent from an EX1 are reversed for their sequence and the interrupt signal is processed earlier by an EX2. In this case, when the EX2 is idle and the interrupt signal is received, a call number sent while being superimposed on the interrupt signal is set to a call number management table and a restoration end signal is returned to the EX1 being a precedence station. Succeedingly, the EX2 checks the normality of the call number. Since the call number is not normal, the EX2 regards it as signal sequence inversion and aborts the address signal.

Title: Hot baking repairing material
Inventor: TERAYAMA SATORU
IPC: C04B35/66
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain a hot baking repairing material which is fluidized in a short time at the time of hot repairing, is fixed rapidly by baking on a damaged part and is excellent in durability by blending refractory aggregate with specified amts. of solid pitch and sodium hydrogencarbonate. SOLUTION: Refractory aggregate is blended with 15-50wt.% solid pitch and 0.1-5wt.% sodium hydrogencarbonate based on 100wt.% of the aggregate to obtain the objective hot baking repairing material. The solid pitch preferably has 80-150 deg.C softening point. Magnesia, alumina, silica, SiC, graphite, fire clay, metallic Si, scrap brick, etc., are properly blended and used as the refractory aggregate. The solid pitch imparts moderate flowability to the repairing material. Since gaseous CO2 generated by the decomposition of the sodium hydrogencarbonate at the time of application causes a porosity to an applied body, a volatile component generated from the pitch is easily released to impart satisfactory suitability to baking, and necessary application time is shortened.
